The header of the form.

<div class="definition">
    String, default = ''
</div>

The header can be simple text or HTML. If you change <span class="argument">.header</span> property, you will need to call
<a class="argument" href="w2form.refresh">.refresh()</a> method to refresh the form. If header is not set it will not be
rendered.
<div style="height: 10px"></div>

Header can be defined during object creation:

<textarea class="javascript">
let form = new w2form({
    name     : 'form',
    header   : 'Form Header',
    formURL  : '/server/path',
    fields: [
        { field: 'first_name', type: 'text', required: true },
        { field: 'last_name', type: 'text', required: true },
        { field: 'email', type: 'email' }
    ],
    record: {
        first_name : 'John',
        last_name  : 'Doe',
        email      : 'jdoe@email.com'
    },
    actions: {
        "save": function () { this.validate(); },
        "reset": function () { this.clear(); }
    }
});
</textarea>

Or any time after the form has been created:

<textarea class="javascript">
w2ui.form.header = 'Grid Header';
w2ui.form.refresh();
</textarea>
